Four stroke good - two stroke bad
All the models we tested in this mower test are four-stroke. CHOICE does not recommend two-stroke engines, no matter how well they perform, as they emit more pollution, burning a mixture of petrol and oil rather than straight petrol. A four-stroke motor typically emits half the carbon monoxide and one-tenth the hydrocarbons that a two-stroke produces.
For example in a previous test on non-mulching petrol mowers the Victa Tornado Classic TCS482 had the same cutting and ease of use scores in our test as its four-stroke cousin, the TCS484. So although it scored well in performance, we could not recommend it on environmental grounds. After this test it was decided that we would no longer test two-stroke varieties.
Mulcher lawnmower brands tested
CHOICE tested 30 petrol-powered mowers and one battery-powered that keep your lawn looking its best. One has a self-propelled drive mechanism and the others are propelled by the user.

How we test
Our CHOICE tester, Peter Horvath, tests the mowers at Tropical Lawns, a turf farm in Cairns, Queensland.
The consistent climate provides plenty of grass to cut all year round. All mowers are weighed and their cutting height range assessed. He checked how close each model can cut along a vertical wall at the front and sides.The numbers listed in the table under (Closeness of cut to a vertical edge in mm) relate to the dimensions of the width of grass left behind after cutting at the front, right hand side and left hand side of the mower.
Ease of use
He rates them for vibration through the handle bar, ease of pushing and manoeuvring, handle comfort, convenience of controls, ease of adjusting the cutting height, catcher convenience and ease of starting.
He tests the lawnmowers for their ability to cut short- and medium-length grass with a catcher, and long grass without a catcher.
In mulching mode, he cuts short and medium length grass and assesses the appearance of the lawn after the short and medium grass cutting tests.
He measures noise at 7.5m and at the operator’s ear level. For a better understanding of how noise relates to everyday sounds, see our article here
He also carries out safety tests, which include measuring blade stopping time and a foot probe safety test.
